signor to Winchester Repeating Arms Company, New Haven, C0nn.,..acorporation of Maryland 'Application June 28,` 1933, SerialfNm 677,9624. v Claims.. (C1.v 20s-473) This invention relates to roller skates andmore particularly to a,roller skate havingimproved adjusting meansl to tthe skate to the shoe :of

the skater.

In carrying out my invention I provide a skate comprising a heel plate,and toe plate having a girder formed integrally with one of said plates,preferably the toe plate. The girder is provided with an elongated slotadopted to receive a b01t carried by the heel plate to adjust the sizeof the skate. I further provide side flanges on the girder which mayextend throughouta portion of the toe plate to stiffen it and produce amore rigid construction.

The girder flanges are provided with longitudinal ribs or grooves vtoincrease the strength 1of the skate. By forming ribs on the ilanges itispossible to employ lighter material in the construction of .the skateand still obtain a rugged construction. 1 f

In one form of the invention, the rear- -truck hangers are provided withinwardly extending lugs suitably spaced from the heel plate toformledges on whichthe girder flanges rest. This provides a more rigidconstruction than would be obtained if these ledges were omitted.- Inanother formof the inventionthe side walls of'thetruck hangers areprovided with ribs which are received in the longitudinal grooves of thegirdenflanges and form guides for the girder.

A further feature of the invention consists in providing indentations inthe truck hangers whereby a more rigid construction is obtained andwhereby the elastic cushion generally employed in skate constructions isrigidly clamped in the truck hanger.

In the accompanying drawing I have shown several forms of the invention.In the drawing,

Fig. 1 is a side elevation of one form of skate, parts being shown insection;

Fig. 2 is a plan view thereof;

Fig. 3 is a transverse, vertical, sectional view on line 3-3 of Fig. 1;

Fig. 4 is a detailed view of the rear truck hanger; and,

Fig, 5 is a transverse, vertical, sectional view (similar to Fig. 3)showing a modified form of the invention.

Referring to the drawing, the reference numeral 1 designates a toe plateand 2 a heel plate o a skate. A girder 3 is formed integrally with oneof the foot plates, preferably being formed integrally with the toeplate as shown. This girder is provided with a longitudinal slot 4.

-A bolt 5 is mounted in an opening in the heel plate and" is adapted topass through the slot 4. A nut 6 is mounted on .the bolt to permit theplates to be` retained in any desired adjusted position.'1 Y. '.TheAgirder is provided with downwardly exoo tending side flanges '7 whichmay be formed integrally with marginal anges. 8 extending throughout aportion of the toe plate. The anges-7 are provided with longitudinalgrooves 9 oni their outer sides forming ribs on the inner 65 sideA ofthese flanges. The ylongitudinal Vgrooves 9 materially. strengthen thegirder and give support-'to the skater at a point where the skate isnormally subjected to. considerable strain. By providing. these groovesand strengthening the 7p girder construction, I find that lightermaterial may be employed in the construction of the skate and at `thesame time-obtain sufcient ruggedness for usual skate use. g

A truckhanger is arranged on each of the 75, footpiecesof -theskate'I'hese truckhangers are essentially of the same construction andthesame reference numerals' will, therefore, be ern-.- ployed to designatethe various parts. Each of the truck hangersconsistsof apair of parallelside 80. plates 1 0. -They are secured to the foot pieces by integralrivet lugs 11 carried on the vupper surfacesofAv thevside pieces andadapted to pass through slots in the foot pieces. After the rivet lugsal'ein position in the slots they are headed 85 over in the usual mannerto secure the truck hangers in place. The side pieces are connected by across member 12 which is preferably arranged at an incline to the planeof the foot pieces and which is provided with front and rear flanges 13and 14. The truck hanger cooperates with a cradle member or axle support15 which is of substantially the same size and arranged parallelthereto. This member is also provided with front and rear flanges 16 and17 adapted to be 95 arranged adjacent the lianges 13 and 14 of the truckhanger. A rubber cushion member 18 is arranged in the space formed bythe truck hanger and supporting member 15 and a cotter pin 19 is passedthrough the rubber pad and through aligned openings in the ilanges 13,14, 15 and 16. The supporting member 15 carries a sleeve 20 adapted toreceive an axle 21 on which the rolls 22 are mounted.

In the form of the invention shown in Figs. 1 to 4 of the drawing theupper portions of the side plates are slightly oiset as shown at 23 andare slightly spaced from the flanges of the girder 3. Beneath thisoffset portion the side plates are spaced from each other a distancesubstantially equal to the width of the girder as lil@ shown in Fig. 3of the drawing. 'Ihe rear side plates are provided With lugs 24 struckinwardly from the body of the material forming ledges upon which theside flanges '7 of the girder are adapted to rest. These ledges arespaced from the top of the side plate a distance equal to the Width ofthe ilange 7 so thatiwith theglower edge of the ilange resting ontheledge thegirder is retained in close contact with the bottom of theheel plate.

In the form of the invention shown in Fig. 5Y of the drawing the sideplates 10 are not provided with the offset portions 23 but extendupwardly' to the heel plate 2 at a distance from each othersubstantially equal to the `t'vidth of girder 3. They are provided withlongitudinally extending grooves 25 on their outer faces adapted to formlongitudinally extending ribs on theirinner faces, which ribs arereceived in the grooves 9 of the flanges of the girder. It will beapparent that this construction provides a guide for thel girder andvadds to the rigidity of the skate.

To'further add to the rigidity of the skate-and permit the use oflighter material in the constrwrtion of the skate without sacriilcingnecessary strength, I provide indentations 26 at the front and rearedges of the cross piece 12 'which connects the side pieces 10 of. `thetruck hanger. Similar indentations may-be provided at the junction ofthe sidewalls 10 and the cross piece 12. These indentations, `'wl'iieharepreferably formed at the-pointwherethe end-ilangeslS anddd are joinedto the body portion of :the cross piece, not only add to the strength ofthe truck henger but also more rigidly-clamp the cushioning padimposition .lhetoe piece is .providediwith the usual clamps 27 mountedonasuitablebracket on the bottom of the toe piece and adapted-totheadjusted by a vkthreaded rodv28l inthe usual manner. ALike-- wise, .theheel piece-'is provided with' theiusual anges 29 to whichra skate strapKnot-shown) 'may be attached in any V:suitable manner,- -The toe platemay also be provided with ribs 30 formed in the metal for the purposeVof strengthening this member and thereby permit theA` 'use of lightermaterial. -1

It will be apparent from the 'foregoing de-` scription that l haveprovided a roller skate which is made of a relatively small number ofparts and which is of simple construction and therefore relativelyinexpensive to manufacture. At the same time the construction providesunusual ruggedness and therefore permits the use of light material inthe manufacture of the skate.
